chain40	df70d69851	bugfix: 修正 cc2650 相容性實作	2024-05-08 00:04:58 +08:00
chain40	440f443a99	feat: 升級 gcc 版本 12.3.1, 升級 gdb 版本 13.2	2024-01-31 23:14:10 +08:00
chain40	32f5fee764	bugfix: 支援不同的 addree type 連線 1. Public address (cc2650 目前使用, 需向 ieee 註冊) 2. Random static address (bmd380 目前使用) 3. Resolvable random private address (未使用) 4. Non-resolvable random private address (未使用)	2024-01-31 23:14:06 +08:00
chain40	7fc5b54c47	feat: 當接收到 notify 時, 會根據不同的 char handle 執行對應的 callback 1. 目前只有 regular_data_char_handle 有實作	2024-01-31 22:50:01 +08:00
Roy_01	370d6cc80f	updated response of disconnection and connection timeout	2023-10-03 16:02:00 +08:00
chain40	d99848592b	bugfix: 修正掉資料的問題 (已排除) 原因: 因為連線後的 connection interval 設為 20ms, 造成 EIS 在 100sps 狀況下會掉資料修正方式: 將連線後的 connection interval 設為 8~10ms, 即可排除 EIS 掉資料的問題其它: 將程式碼優化調整為 -O0, 利於程式碼除錯	2023-08-15 23:30:50 +08:00
chain40	401c592281	bugfix: 修正掉資料的問題 (未解決, 僅降低發生率) 1. 程式優化為 -O0, 所以效能受限！將優化改為 -O2 可大幅提升效能 2. 由於 gpiote 中斷有使用到 freertos api, 所以 gpiote 中斷優先權必需低於 configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY, 所以將 gpiote 優先權修改為 _PRIO_APP_MID 可排除掉資料的問題 3. 將 mem_drv_stream 的 buffer size 調整為 4096 bytes (確保 streambuffer 不會被塞爆)	2023-08-14 22:37:10 +08:00
chain40	415f4adfe9	bugfix: 修正自動結束的mode, 有發現沒有收到notify的最後一筆資料的問題 1. 原本是要收到 4 筆以上的資料才上寫入 sram, 現在只要收到 1筆資料就可以寫入 sram, 並切換 sram	2023-08-14 13:07:38 +08:00
chain40	9fc58b51fe	Refactoring: 當 on_ins_write_char() 寫入資料如果發生錯誤, 會在 rtt viewer 顯示	2023-08-14 10:48:10 +08:00
chain40	508ac99c0d	bugfix: 修正當連線成功之後, 如果重複連線會發生錯誤的問題	2023-08-14 10:45:26 +08:00
chain40	6158961dcf	bugfix: NRF_BLE_GQ_QUEUE_SIZE 太小只有 6 bytes, 所以當 characteristic 寫入大於 6 bytes 會寫入失敗 1) NRF_BLE_GQ_QUEUE_SIZE 改為 256 2) NRF_BLE_GQ_GATTS_HVX_MAX_DATA_LEN 改為 256 3) NRF_BLE_GQ_GATTC_WRITE_MAX_DATA_LEN 改為 256 4) NRF_BLE_GQ_DATAPOOL_ELEMENT_COUNT 改為 32 5) NRF_BLE_GQ_DATAPOOL_ELEMENT_SIZE 改為 256	2023-08-14 10:43:53 +08:00
